BACKGROUND

1. Technical Field

The present disclosure relates to mounting apparatuses for attaching electronic components to devices such as computer systems and, more particularly, to a mounting apparatus for mounting a power supply to a computer system.

2. Description of Related Art

Generally speaking, a power supply is a necessary electronic component to be assembled in a computer enclosure. The power supply is often directly attached to a rear panel of the computer enclosure via a plurality of screws installed from inside of the computer enclosure. Therefore, space in the computer enclosure must exist for assembling or disassembling the power supply via a tool such as screwdriver. However, while more and more electronic components are mounted in the computer enclosure, the size of the computer enclosure becomes smaller and smaller, thereby, the operation of assembling or disassembling the power supply in or from the computer enclosure becomes inconvenient.

What is desired, therefore, is an apparatus for mounting a power supply which overcomes the above-mentioned shortcoming.

The computer enclosure 10 includes a first sidewall 12, a top wall 30, a rear wall 20, and a second sidewall 32 detachably mounted to the top wall 30 and the rear wall 20 and opposite to the first sidewall 12 to form a generally rectangular enclosure 10. A first protrusion 14 protrudes toward the second sidewall 32 from the rear end of the inner surface of the first sidewall 12, adjacent the top wall 30. A plurality of first latching slots 16 is defined in the first protrusion 14, facing the rear wall 20. A plurality of mounting holes 18 is defined in the first sidewall 12 below the first protrusion 14. The rear wall 20 defines an opening 23 therein, adjacent the top wall 30, for the power supply 100 passing therethrough. A plurality of fixing holes 25 is defined in the rear wall 20 around the opening 23. A flange 27 perpendicularly extends from the rear wall 20, opposite to the first sidewall 12. A locking hole 28 is defined in the flange 27, adjacent the top wall 30. A mounting hole 29 is defined in the flange 27, adjacent and below the locking hole 28. A plurality of bridge-shaped securing portions 34 protrudes from an inner surface of the second sidewall 32.

The bracket 40 includes a bottom plate 42, and first and second side plates 48, 54 perpendicularly extending down from opposite sides of the bottom plate 42. A plurality of parallel second protrusions 44 protrudes up from the bottom plate 42. A second latching slot 46 is defined in the rear end of each second protrusion 44. A second connector 50 electrically connected to a printed circuit board (not shown) of the computer system is mounted to a front end of the bottom plate 42, for engaging with the first connector 102 of the power supply 100. A plurality of mounting holes 52 is defined in the first side plate 48. A plurality of securing holes 56 is defined in the second side plate 54. A mounting hole 58 is defined in the rear end of the second side plate 54.

The board 60 is attached to a rear side surface of the power supply 100, and defines a vent 74 in a center thereof, corresponding to an air outlet (not shown) of the power supply 100. A first tab 62 perpendicularly extends from one end of the board 60. A second tab 70 perpendicularly extends from opposite end of the board 60. A third tab 66 perpendicularly extends from the bottom side of the board 60. A plurality of L-shaped hooks 64 and 68 respectively protrudes from the first and third tabs 62 and 66. An elastic locking portion 72 extends from the second tab 70. A plurality of fixing holes 78 is defined in the board 60 around the vent 74 thereof. A through hole 76 is defined in the board 60, for a plug (not shown) of the power supply 100 being exposed therethrough.

Referring to FIGS. 4-6, in assembling the computer enclosure 10 and the bracket 40, the bracket 40 is placed between the first sidewall 12 and the flange 27, with the rear end of the bracket 40 resisting against the inner surface of the rear wall 20. A plurality of screws (not shown) is inserted through the plurality of mounting holes 52 of the bracket 40 to engage in the plurality of mounting holes 18 of the first sidewall 12, to fix the bracket 40 to the first sidewall 12. A screw (not shown) is inserted through the mounting hole 58 of the bracket 40 to engage in the mounting hole 29 of the flange 27, to fix the bracket 40 to the flange 27. The second sidewall 32 is attached to the flange 27 and the top wall 30, opposite to and parallel with the first sidewall 12, with the plurality of securing portions 34 engaging in the plurality of securing holes 56 of the bracket 40. As a result, the first and second sidewalls 12 and 32 sandwich the bracket 40 therebetween.

In assembling the power supply 100, a front side of the power supply 100 passes through the opening 23 of the rear wall 20 to enter into the computer enclosure 10. The power supply 100 is moved further along the bottom plate 42 of the bracket 40, until the plurality of hooks 64 and 68 of the board 60 engages in the plurality of first and second latching slots 16 and 46, respectively. The first connector 102 of the power supply 100 engages with the second connector 50. The locking portion 72 of the board 60 is engaged in the locking hole 28 of the flange 27. Therefore, the board 60 resists against the rear wall 20, to cover the opening 23, with the plurality of fixing holes 78 of the board 60 aligning with the plurality of fixing holes 25 of the rear wall 20. A plurality of screws is inserted through the plurality of fixing holes 78 to engage in the plurality of fixing holes 25, to fix the board 60 to the rear wall 20. Therefore, the power supply 100 is assembled.

In disassembling the power supply 100, the plurality of screws fixing the board 60 to the rear wall 20 is released. The locking portion 72 is disengaged from the locking hole 28. Thus, the power supply 100 can be removed from the computer enclosure 10 through the opening 23 of the rear wall 20.
